IMPROVEMENT IN RAILWAY-RAILS.

Specification forming part of Letters Patent No. 144,221, dated November4, 1873; application filed May 9, 1873.

To all whom it may concern:

Be it known that I, M. It. PERKINS, of Portsmouth, county of Itockinghamand State of New Hampshire, have invented certain new and usefulImprovements in Railroad-Rails, of which the following is aspecification:

The object of my invention is to produce a compound rail, simple andcheap in construction, that will relieve machinery from the injuriouseffect of concussion, and allay the action of frost, by the combinationof the sections 1 and 2 with an intervening continuous layer ofwater-proof paper of sufficient thickness, as shown in the accompanyingdrawing.

The accompanying drawing represents a cross-section of my compound rail.

1 represents the lower part or section of the rail, consisting of thebase and shank, having a head or broad bearing-surface, 6, for the capor crown 2 to rest upon. This section is at tached to the cross-ties inthe usual manner, and may be made of. the cheaper grades of iron.Fitting over the head or broad bearingsurface 6 is the upper part orsection 2, consisting of the cap or crown, with a downward extension, 7,for securing the section to the shank by means of bolts 3. This sectionmay be made of iron or steel. Extending continuously throughout, betweenthe sections 1 and 2, is a packing, 5, made of water-proof paper, asshown in drawing. The function of this continuous packing is fourfold,to wit: It prevents lateral and vertical concussion and rat th'n g,obviates the action of frost, and prevents any wear from friction. Thenature of the material prevents its gathering moisture, and sec tions 1and 2 are so constructed as to drain the packing, preventing thelodgment of moisture to be affected by frost.

I am aware that rubber has been used heretofore as a cushion to ease theeffects of vertical concussion, but its disadvantages are such as torender its use; impracticable. The heat of a summer sun, attracted bythe iron rails, soon softens it, and the action of frost makes it rottenand brittle, and it looses its elasticity and becomes useless.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The section 1, having broad bearing-surface 6, in combination withsection 2 and paper packing 5, extending continuously between thesections, arranged to prevent lateral as well as vertical concussion,and neutralize the action of frost, heat, and moisture, substantia-llyas shown and described.

In testimony that I claim the foregoing as my invention I hereunto affiXmy signatin'e.
